Abstract

The invention discloses molybdenum-tungsten alloy which comprises the following raw materials in parts by weight: 100-102 parts of molybdenum, 80-82 parts of tungsten, 2-4 parts of magnesium, 1-3 parts of zinc, 4-6 parts of hafnium nitride, 2-4 parts of yttrium oxide, 1-3 parts of thulium, 1-3 parts of terbium, 1-3 parts of erbium, 4-6 parts of polycrystalline mullite fibers, 2-4 parts of titanium oxide, 2-4 parts of tricobalt tetraoxide and 5-7 parts of chromium sesquioxide. The molybdenum-tungsten alloy is high in strength.

Description

technical field [0001] The invention relates to a molybdenum-tungsten alloy and a preparation method thereof. Background technique [0002] Molybdenum-tungsten alloys can be used at higher temperatures than molybdenum or molybdenum alloys. For example, when molybdenum-tungsten alloy is used as electrode, orifice and thimble parts in the wave furnace for the production of high melting point refractory ceramic fibers, its service life is much longer than that of pure metal molybdenum products. Mo-30W has higher resistance to zinc liquid corrosion than pure metal molybdenum, and is mostly used in certain corrosion-resistant parts of zinc liquid temperature measuring tubes, zinc liquid pump rotors and zinc smelting furnaces. Molybdenum-tungsten alloy can also be used for gas rudders and guard plates of solid rocket motors due to its high melting point, good ablation resistance and flame erosion resistance of solid particles. The nominal composition of commonly used molybdenum-...
